摘要
对于艏艉破冰模式的极地船舶,规范没有给出冰带划分方法,仅仅提到艉部破冰参考艏部破冰区域划分,但由于艉部线型与艏部线型差距较大,故并不能很好地适用。文章以一艘PC4级110 kt极地原油船为例,针对艉破冰模式进行冰区带划分,并针对冰载荷产生的弯矩剪力对船体总体强度的影响进行了分析。
For the polar vessels in the bow and stern ice breaking mode, the method of dividing the ice zone is not given in detail in the specification, only the division of the ice breaking area of the stern references to bow areas is mentioned. However, due to the larger difference between the hull stern line and the bow line, it is not very suitable. The paper takes a 110 kt polar crude oil ship of PC4 class as an example, and divides the ice zone under the stern ice breaking mode. In addition, the influence of bending moment and shear force generated by ice load on the overall strength of ship is also discussed in this paper.
